FOOD-SLICER.

, SPECIFICATION forming part of Letters Patent No. 680,032, dated August 6, 1901.

Application filed December 7, 1899. Serial 110 739,539- (No model.)

My invention relates to certain improvements in machines for slicing or shaving food. My invention is especially adapted for shaving dried beef and other meats and cutting bread.

The object of my invention is to simplify the working parts of the machine and to provide feed mechanism which can be adjusted so as to shave the beef to any thickness desired.

In the accompanying drawings, Figure 1 is a plan view of my improved food slicing or shaving machine. 3 is an end View. Fig. 4 is a sectional view on the line 4. 4, Fig. '1. Fig. 5 is a detail view showing the knife shaft and its bearings. Fig. 6 is a sectional view showing the friction feed mechanism. Fig. 7 is a section on the line 7 7, Fig. 6. Fig. 8 is a section on the line 8 8, Fig. 7. Fig. 9 is a perspective view of the pawl-carrier of the friction-feed. Fig. 10 is a perspectiveview of the shifting-pin for the pawl-carrier. Fig. 11 is a view of the feed-lever, and Fig. 12 is a modification of the pawl-carrier-shifting pin.

A is the frame of the machine, having in the present instance a trough A, which is supported at its outer end by a foot a. The frame A is preferably of the shape shown clearly in Fig. 3, being flanged and forming a casing around the cutting mechanism, also having a foot a.

A is a cover-plate which is hinged to the frame A at 0, and is held to the frame by a latch a, which passes in front of a lug a on the cover-plate, so that by turning this latch- Fig. 2 is a side view. Fig..

blade B In the present instance there is only one 'arm and one knife-blade; but it will be understood that two or more knife-blades may be used without departing from my invention.

It will be noticed that the cover-plate A rests between. the handle B and the knifecarrier B and is recessed at a the recess extending to the shaft. By this construction the knife is inclosed; yet the cover-plate can be moved on its pivot or entirely removed without detaching the handle. 4

The shaft B has a screw-threaded portion, and on the screw-threaded portion are two nuts 0 c. The nut c bears against the-cam G and has a set-screw c and the nut c bears against the bearing 12 and has a set-screw 0 so that on adjusting these nuts on the shaft any wear of the knife-blade or of the bearings can be taken up, since the shaft can be moved longitudinally thereon and locked in any position desired. By simply backing oi the set-screws and the screw that holds the cam G to the shaft the shaft can be entirely withdrawn from the machine for the purpose of repairing or removing the knife, if necessary.

The knife is curved and shears past the end of the trough A of the frame, so that when the beef or other food is fed forward in the trough it will be sliced by the knife, and the sliced portions will fall onto the table on which the machine is mounted or through an opening in the table into a suitable receptacle', if desired.

In order to feed the material forward uniformly, so that the slices will be properly cut, I mount on the fixed shaft D, Fig. 2, a pusher E, having a box e,- through which the shaftD extends. Extending also through this box c is a feed-rod F,which is reciprocated,and friction mechanism" is provided, so that when the rod F is reciprocated the pusher E will be moved intermittently forward.

The cam G on the shaft B acts against one arm h of a lever l-I. (Shown clearly in Fig. 11.) This lever is pivoted at h to the frame of the machine,and on the lever is a set-screw 71. which strikes against the frame and limits the movement of the lever in one direction. The long arm h of the lever has a pin, which engages a collar f on the rod F, so that as the cam is revolved by the shaft 3 it forces the short arm of the lever out and draws the rod F toward the head of the machine, causing the pusher to move forward. A spring h, which is coiled around the pivot h, presses against the rear of the arm h of the lever and tends to force the rod back. Thus the roller on the end of the arm h of the lever is kept in contact with the cam. I

In order to vary the movement of the rod F, a set-screw k is used, which strikes the casing,limiting the rearward movement of the rod. By turning this screw either forward or backward the amount of movement of the rod is regulated, and thus the feeding mechanism for feeding the material toward the knife can beset in any desired position and the slides out can be any thickness desired.

The friction-feed mechanism I prefer'to use is clearly shown in Figs. 6, 7, 8, 9, and 10..

In the box e of the pusher E are two tapered sockets e '6, through which pass the rod F and shaft D, respectively. Mounted back of, the washer vis a spring is, resting against the interior of'a cap 6 1, secured to. the 1 box e by screws e" or other fastenings, and on 2 the shaft D is a washer I0 and back of this: washer is a spring 15 also resting within the t recess in the cap 6 The halls are so fitted to the box that when they are pressed into position, as shown in Figs. 6 and 8, they are confined between the rod and the shaft and the tapered walls of the j When the rod F is moved forward in;

box. the directionof the arrow, Fig. 6, the pusher E will move with it, as the balls forma fri'c- 1 tion-cou pling between the shaft and the box, I. and as the pusher moves forward it will slide I freely on the fixed shaft D, as the tendency. of the balls will be to move from the cavities t and clear of the walls of the socket'e of the;

box e; but on the return movement of the 'rod F- the balls i will hold the pusher rigidly to the fixed shaft D, while the rod F will slide freelyin the box. Thus an intermittent forward feed is given to the pusher. When the pusher reaches a certain point in its forward; movement, it is automatically stopped by sim- 5 ply reducing the rod at f, Fig. 2, so that the. balls cannot be jammed between the rod and.

opposite end of the casing to which it has. been fed forward, I provide a push-bolt M,f Fig. 10, which rests back'of the carrier I and when pushed will force it out of the sockets e e so as to free the balls, and the pusher is. then free to be moved to'any point desired.

The springs K K return the carrier-"and bolt as soon as released.

In some instances I may use a cross-bolt M, Fig. 12, having a beveled portion'm resting back of the carrier, so that when the bolt is pushed in it will force the carrier out of the sockets. A spring 112. will returnthe bolt as soon as released Thus it will be seen that I provide feed mechanism that can be adjusted to intermittently feed the pusher forward, and the machine can be set so that the food can be cut to any thickness, and I provide a simple frictio'n feed mechanism and a simple method of adjusting the parts. Furthermore, Idispense with the long knife-shaft of the machine, using a short shaft, which is not in the way and which can be adjusted longitudinally, so as to adjust the knife toward and from the cut ting-face of the machine.

I claim as my invention- 1. The combination in a machine for slicing food, of aframe, a trough projecting rearwardly therefrom, a shaft shorter than said trough having one end supported in a bear ing in said frame, an arm supported on the frame and providing a bearing for the other .end of the shaft, a knife on the shaft on the "outside of the frame, a cam also on the shaft, between the two bearings, a lever actuated bythe cam, a pusher in the trough, a feedrod connected to said lever, and frictional gripping mechanism between it and said rod whereby the pusher will be intermittently fed forward when the shaft is rotated, substantially as described. v

2. The combination of a frame, a shaft mounted thereon, a knife carried by'the shaft, a cam also on the shaft, a lever pivoted to the frame and constructed to be actuated by the cam .a feed-rod connected to the lever,afixed shaft, a pusher having a box with a tapered socket, a carrier in the said socket through which pass the feed and the fixed rod, balls in the socket and a spring constructed to keep the same therein, the balls and socket being constructed so that the pusher is fed forward when the knife is rotated, substantially as described. I

3.
